Title: Method for inspecting surface of photographic paper
Inventor: TAKAHASHI TOKUJI
IPC: G01N21/892
Filed: 1983-07-04
Abstract: PURPOSE:To improve accuracy in detecting defects yielded on the surface of photographic papers, by detecting diffused reflected light from the defective parts on the surface of the photographic paper, and finding the defects by the various change in the diffused reflected light. CONSTITUTION:Light from a light source 10 is reduced by an ND filter 11 and polarized by a rotary scanner 12. The surface of color photographic paper A is scanned by the light through an Ftheta lens 13. As shown in the Figure, in the normal reflected-light region (a), the changes in amounts of light for silk A1 and glossy A2 of the color photographic paper are both large. In the diffused reflected-light region (b), however, the change in amount of light is small. A light receiving part for diffused reflected light 17 is arranged at a position, where the diffused light is detected, as a light receiving part. In this part, a plurality of photomultipliers and preamplifiers, which are operated by a high voltage power source 18, are enclosed. The outputs of the preamplifiers are made to pass an adding amplifier 19 and an HPF20, and a detected signal 21 is outputted. By receiving the light by the diffused reflected-light region in this way, the accuracy of a detect signal 22 is improved, and the detection of the defect is performed accurately.

IPC: H01L31/08
Filed: 1979-09-19
Abstract: PURPOSE: To easily form a photoreceptor almost free from deterioration due to humidity, by washing a photoconductive powder after applying AC high voltage or intermittent DC high voltage to the powder.  
     CONSTITUTION: A photoconductive powder, such as CdS obtained by the conventional method is dispersed into an equal amount of isobutyl alcohol, coated on an aluminum plate or a resin film, and dried, or the powder is scattered to form a 10W100μm thick layer. Another resin film is overlaid on this layer or not overlaid, and 0.5W5kV AC high voltage, or DC high voltage is applied intermittently to the powder layer by shifting a conductive rubber roller as an electrode at 0.3cm/sec speed for 12sec/cm 2  in total. Alternatively, 5W7kV voltage is applied with a corona discharger located at 2W3cm distance from the powder. After application of the voltage the CdS powder is sufficiently washed with water, and further washed in presence of ion exchange resins to remove ions produced by the voltage application, thus permitting superior photoconductivity to be retained even under high humidities in repeated uses for a long term.

Title: Dynamic memory refresh circuit
Inventor: ISHIDO TEIICHI
IPC: G11C11/34
Filed: 1984-06-14
Abstract: PURPOSE:To perform efficiently refresh of a DRAM and the DRAM access of a CPU by dividing memory areas to even areas and odd areas to avoid the competition on the memory between the access cycle of the CPU and the refresh cycle. CONSTITUTION:When a CPU 7 accesses an even address, the address from the CPU 7 is given to a DRAM 4 for even address, and the normal memory R/W cycle is executed. At this time, the signal on a line 1 becomes ''1'' to make refresh of a DRAM 1 possible, and an address where contents should be refreshed is given to the DRAM 1 from a counter circuit 6 by a 2-1 selector circuit 5. The counter circuit 6 is counted up simultaneously with the end of refresh to generate an address for the next refresh cycle. Though the CPU 7 accesses the even address, a memory request control signal is sent to the DRAM 1 for odd address also for the purpose of performing refresh.

Title: High definition picture input device
Inventor: YAMASHITA TAKEHIRO
IPC: G02F1/135
Filed: 1994-06-03
Abstract: PURPOSE:To obtain a high quality picture by providing a means adjusting an incident luminous quantity to the device to correct a color temperature characteristic of a light source and a spectral sensitivity characteristic of an optical sensor thereby matching an exposure range and widening a range of color reproducibility. CONSTITUTION:A filter adjusting proper exposure for R, G, B colors is provided. That is, a filter 50 is placed before a 3-color separate filter to convert the signal to have an optional color temperature characteristic. In this case, a color temperature conversion film or the like having a prescribed transparent spectral characteristic is employed for a filter in use. Furthermore, since an optical sensor 20 has a spectral characteristic having a high G sensitivity, excellent picture recording independently of the color temperature characteristic of the light source or the spectral sensitivity of the optical sensor is implemented by taking the characteristic being the result of product of two characteristics into account so as to locate the proper color filter having a proper transparent spectral characteristic before the color separate filter.

In the case of setting the test mode, the distributed controller 2 receives a control command from the high order controller 3 only when a test mode signal in the transmission signal 6 is set to the test mode and thereafter processes the command. For example, operation installations 1-1-1-m use distributed controllers 2-1-2-m and a remote supervisory controller 3-1 to make usual operation from a remote control station 5. Then the installation 1-n uses the distributed controller 2-n and the central supervisory controller 3-2 to conduct the test.
